MANUALLY OPERATED AIR VALVE AND ACTUATOR IN COMBINATION CONTROL A HYDRAULIC SPOOL VALVE FOR MANEUVERING HEAVY EQUIPMENT |
摘要 |
<p>A proportional remote control having an air regulating controller and an air operated actuator that have matched components to provide a true linear control of the displacement of a valve spool in proportion to lever displacement on the controller. Minimal displacement of the hand lever applies an initial stepped output pressure to the actuator which moves the spool just short of fluid flow. The controller regulates the air pressure applied to the actuator from the initial stepped pressure to its maximum output in proportion to the displacement of its control lever.</p> |
